3. Preventing Moisture Damage: Spring showers may bring May flowers, but they can also wreak havoc on your home if moisture finds its way indoors. Insulation plays a crucial role in preventing moisture buildup and condensation, which can lead to mold growth, rot and structural damage. By maintaining your insulation, you can safeguard your home against water-related issues and preserve its integrity.

4. Allergy Relief: Springtime allergies can make life miserable for allergy sufferers, but did you know that proper insulation can help reduce indoor allergens? By sealing gaps and cracks where allergens can infiltrate, you can create a healthier indoor environment and breathe easier during allergy season.

So, where should you start with your spring insulation inspection? Begin by checking the insulation in key areas of your home, such as the attic, walls and crawl spaces. Look for signs of damage, compression or moisture intrusion, and consider hiring a professional like Lewis Insulation if you’re unsure about the condition of your insulation.

The Basics of Cellulose Insulation

When it comes to creating a comfortable and energy-efficient home, insulation plays a crucial role. Among the wide variety of insulation materials available, cellulose insulation stands out as an environmentally friendly and effective option. At Lewis Insulation, we have decades of experience with insulation, and specifically are proud to offer cellulose insulation to Rogers and the surrounding Twin Cities area. As experts in the topic, we have highlighted the key points to know about cellulose insulation below!

What is Cellulose Insulation?

Cellulose insulation is a type of thermal insulation made primarily from recycled paper, which is treated with fire-retardant chemicals for enhanced safety. This eco-friendly composition is a significant departure from traditional insulation materials like fiberglass or foam board, which often rely on non-renewable resources.



One of the standout features of cellulose insulation is its commitment to sustainability. This insulation is typically composed of up to 80% recycled materials, diverting tons of waste from landfills and giving it a new purpose. This dedication to recycling not only reduces environmental impact but also aligns with the growing demand for eco-conscious building practices.

Thermal Performance

Cellulose insulation is often picked for its excellent thermal performance. It effectively slows down the transfer of heat, providing a barrier against both extreme cold and scorching heat, making it a prime example of what insulation should do for your home. This characteristic makes it a versatile choice for homes located in various climates, from chilly northern regions to hot and humid southern areas.

Effective at Filling Gaps

Unlike some other insulation materials, cellulose is particularly adept at filling gaps and voids in walls, ceilings and attics. This unique property ensures more comprehensive coverage, reducing the likelihood of air leaks and improving overall energy efficiency. The result is a home that remains comfortable year-round, with reduced energy consumption and lower utility bills.

Fire Safety Measures

Safety is often another large concern when it comes to home insulation. Cellulose insulation addresses this concern through the incorporation of fire-retardant treatments during the manufacturing process. This treatment not only enhances the material’s resistance to combustion but also contributes to a safer living environment.

Home Insulation and Energy Efficiency: Myths vs. Facts

Homeowners are often bombarded with advice on how to make their homes more energy efficient. One of the most common recommendations is to improve insulation. However, there are many myths and misconceptions surrounding insulation and its impact on energy efficiency. At Lewis Insulation, we understand home insulation in Plymouth and want to debunk some of the most common myths.

Home Insulation and Energy Efficiency

Myth 1: All Insulation is the Same

Fact: Not all insulation materials are created equal. Different types of insulation have varying levels of effectiveness and suitability for specific areas of your home. There are many different types of insulation materials available, such as fiberglass, cellulose, foam board and spray foam – each with their own pros and cons.

Myth 2: Insulation Alone Will Drastically Reduce Energy Bills

Fact: While proper insulation is a crucial component of energy efficiency, it’s not a standalone solution. A holistic approach to energy efficiency is imperative. This approach often includes factors like air sealing, efficient HVAC systems and lifestyle choices. It’s essential to know that insulation works in conjunction with these elements.

Myth 3: Adding More Insulation is Always Better

Fact: Over-insulating a space can be as problematic as having insufficient insulation. There is an insulation “sweet spot” in each home, where too much insulation beyond that can lead to issues like moisture problems and reduced indoor air quality.

Myth 4: Insulation Stops Heat Transfer Completely

Fact: Insulation slows down heat transfer; it doesn’t stop it entirely. Insulation helps to address the principles of heat transfer (conduction, convection and radiation), however, it does not fully stop heat from transferring.

Myth 5: Insulation is a One-Time Investment

Fact: Insulation can degrade over time and lose its effectiveness. Regular maintenance and insulation inspections are required to ensure it continues to perform optimally.

Myth 6: Insulation Doesn’t Matter in Warm Climates

Fact: Insulation is beneficial in both cold and warm climates. Insulation helps maintain comfortable indoor temperatures and reduce cooling costs in hot climates by keeping conditioned air in and outdoor heat out.

In the world of home energy efficiency, misinformation abounds. By dispelling these common myths and presenting the facts about insulation and its role in reducing energy consumption, you can make more informed decisions about how to improve your home’s efficiency. Remember that achieving a truly energy-efficient home involves a combination of factors, and insulation is just one piece of the puzzle. Stay informed and consult with the professionals at Lewis Insulation when making decisions about insulation upgrades to ensure you get the best results for your home and budget.

4 Myths About Attic Ventilation

One of the most commonly misunderstood things about the home, attic ventilation comes with its own fair share of myths. As attic ventilation experts in Minneapolis, Lewis Insulation is here to discuss these myths! If you have any questions about attic ventilation, contact us.

Attic ventilation is an important topic to understand as it’s estimated that about 90% of homes have unreasonably high levels of moisture. Proper ventilation can protect your belongings, your roof and your insulation.

1. The More Attic Ventilation, The Better

One of the myths we hear the most frequently is that more attic ventilation is always better. Unfortunately, just as is the case with air conditioning units and furnace capacities – more is not always better. While too little attic ventilation is definitely an issue, having too much may be an even bigger risk.

Roof vents create more access to the inside of your home, so having too many can increase the risk of leaks, weak spots for storm damage, or sparks entering your home and causing destruction on the inside.

This leaves the question: how much ventilation is just right? Unlock Goldilocks who needs to test out multiple options to make the right choice, your decision is simpler – just call your local professional! We are able to identify the proper amount of attic ventilation to keep everything just right.

2. Roof Vents Equals Attic Ventilation

Simply having roof vents does not mean that you have adequate attic ventilation. Depending on your home, roof and type of roof vents, your roof vents may not do much of anything for your attic ventilation. Each home and roof is unique, so the best way to ensure that you have proper attic ventilation is to hire a professional to install a ventilation system that will work for you.

3. Roof Vents Allow Warm Air to Escape During Winter

Many people fall into the belief that attic ventilation causes lower energy efficiency due to warm air rising. However, if your warm air is rising straight up to your attic and out of roof vents, you have bigger problems than attic ventilation.

Chances are, if warm air is escaping through roof vents during the winter, you have an insulation problem. Unfortunately, insulation problems can also increase moisture – meaning that attic ventilation remains a considerable concern as well.

4. Only Warmer Climates Need Roof Vents

This statement normally originates from people who assume roof vents are only to increase energy efficiency in the summer by allowing heat to escape – and while this is a benefit of good attic ventilation, there are other pieces that are better designed for energy efficiency. Shingle color, sun exposure and insulation each contribute more to energy efficiency.

However, attic ventilation is still very necessary, even in cooler climates. In fact, colder climates tend to benefit even more from proper ventilation than warmer ones. Colder climates have to worry more about condensation in the attic due to the chill outside, meaning that proper ventilation to keep moisture levels low is infinitely more important.

Now that you are armed with a better understanding of attic ventilation for your home in Minneapolis – are you ready to call an expert to make sure your ventilation is up to its job? Call Lewis Insulation today at 763-477-2612 or contact us!
